8 Star Alaska LLC Gas Treatment Plant PSD Permit Construction Extension

8 Star Alaska LLC is proposing to construct the Gas Treatment Plant (GTP) located on Alaska’s North Slope in the Prudhoe Bay Unit (PBU), approximately 8.5 miles north-northwest of Deadhorse. The GTP is part of one integrated liquefied natural gas (LNG) project to bring natural gas from Alaska’s North Slope to international markets in the form of LNG, as well as for in-state deliveries in the form of natural gas. The GTP will take gas from the PBU and the Point Thomson Unit (PTU) and treat/process the gas, before it is sent 807 miles through a 42-inch diameter pipeline to the Liquefaction Facility in Nikiski on Alaska’s Kenai Peninsula for export in foreign commerce.

Construction Permit No. AQ1524CPT01 issued on August 13, 2020 authorized the installation of twelve (12) cogeneration gas-fired turbines for compression with supplemental firing duct burners and waste heat recovery units, six (6) simple cycle gas-fired turbines for power generation, eight (8) gas-fired heaters, one (1) black start diesel-fired engine generator, three (3) diesel-fired firewater pump engines, two (2) diesel-fired emergency generators, and eight (8) natural/process gas flares. Construction never commenced under Construction Permit No. AQ1524CPT01 and the deadline to begin construction under both the permit and extensions were not met. Subsequently, an application for Construction Permit No. AQ1524CPT02 was submitted on February 11, 2025, to update certain elements of the original application with more timely information.
